BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a device for containing and controlling extreme pressure used, for example, in a resin transfer system, and method of use thereof.

2. Background of the Related Art

There is a general need in the art of pressurized resin transfer molder and other product manufacture to provide containment vessels or chambers for containing up to extreme pressures resin and other product material contained therein. In the prior art, portions of such vessels or chambers are typically clamped or bolted together, and containment pressures are created by, for example, mechanically or hydraulically applying a press-driven force to the chamber or vessel contents. Problems with this approach include failures of the clamps or bolts and imprecision in the pressures produced and distributed within such chambers or vessels.

SUMMARY OF THE INVENTION

The present invention overcomes the above identified problems, as well as others, by providing a pressurizable chamber device or containment vessel and method of use thereof. In one embodiment, the present invention provides a vessel or chamber device that includes two chamber portions, also interchangeably referred to herein as a “first portion” (or “lid portion” or “top portion”) and a “second portion” (or “base portion” or “bottom portion”), and a “ring portion,” also interchangeably referred to herein as a “nut portion.” In one embodiment, the lid portion and the base portion each include concave surfaces that matingly fit together, such that an internal chamber is formed by the combined concave surfaces of the lid and base portions when fit together.

In one embodiment, the lid and base portions each include at least one outer flange having a groove therein, such that a flexible seal element is fittable into the groove of both the lid portion and the base portion when matingly fit together, the flexible seal element maintaining a gap between the face of the lid portion and the face of the base portion when uncompressed, and the flexible seal element being compressible, such that, upon the lid portion and the base portion being drawn toward one another, the seal element is compressed, reducing the gap between the lid portion and the base portion, and thereby tightly sealing the internal chamber formed by the concave surfaces of the lid portion and the base portion. The lid and base portions include features to matingly engage the nut portion, such that engagement thereamong draws the lid portion and the base portion toward one another, tightly sealing the formed internal chamber. A pressure, such as a resin pressure that may be precisely regulated (e.g., via openings to the internal chamber and lines or other conduits connectable thereto for delivering pressurized fluid and/or other materials for use inside the internal chamber), may then be applied, for example, to a mold contained within the chamber, such as a mold containing resins and fibers for producing a molded part or other product.

In one embodiment, the outer flange of each of the lid portion and the base portion includes a plurality of teeth (also referred to interchangeably herein as “toothed extensions” or “dogs”) extending therefrom, with a plurality of wedges being attached to or comprising each of such teeth, one wedge for each toothed extension. In other embodiments, only a portion of such teeth include wedges.

In a first exemplary embodiment of the present invention, the nut portion is ring-shaped, having an interior surface that includes a plurality of nut teeth arranged in two rows extending from the interior surface, a first row being located near a first side edge of the nut portion and the second row being located near the second side edge of the nut portion. In this embodiment, each nut tooth has an attached wedge, the attached wedges extending from the side of a nut tooth to which the wedge is attached in a direction opposite the side of the nut tooth located near the side edge of the nut portion. In other embodiments, only a portion of such nut teeth include wedges.

In the first exemplary embodiment, the top and base portions have generally circularly shaped flanges, and each row of the nut teeth is spaced such that the teeth extending from the generally circular flanges of the top and base portions may be passed therebetween into the inner portion of the nut portion, and, upon rotation of the nut portion relative to the top and base portions, the wedges on the nut teeth and the wedges on the flange teeth meshably engage, such that the top portion and the base portion are compressibly drawn toward one another between the two rows of nut teeth via passing of the wedges on the flange teeth of the top and base portions past the wedges on the nut teeth.

In the first exemplary embodiment, the rotation of the top and base portions relative to the nut portion may be made in any suitable manner, such as by fixably holding the position of the base portion and applying hydraulic pressure to the lid portion, such that rotation of the lid portion occurs relative to the base portion, the rotation of the lid portion tending to be opposed by the nut portion via the lid portion flange wedges engaging a first row of the nut wedges and the second row of nut wedges oppositely engaging the base portion flange wedges. Similarly, the top and base portions may be fixably held, for example, and the nut portion rotated relative thereto, such as via application of a hydraulic pressure.

In a second exemplary embodiment of the present invention, the base and lid portions have flanges extending on each of at least one pair of parallel sides, and the nut portion has at least one pair of parallel sides. Each side of the pair of parallel sides of the nut portion has a pair of generally parallel rows of spaced teeth, arranged in two rows extending from the interior surface, the first row being located near a first edge of the nut portion and the second row being located near a second edge of the nut portion. Each nut tooth has an attached wedge, the attached wedges extending from the side of each nut tooth to which the wedge is attached in a direction opposite the side of the nut tooth near the side edge of the nut portion.

The flange teeth for the base and lid portions likewise each include attached wedges, each row of the nut teeth also being spaced, such that the teeth extending from the flanges of the top and base portions may pass therebetween into the inner portion of the nut portion, and, upon sliding of the nut portion relative to the top and base portions, the wedges on the nut teeth and the wedges on the flange teeth meshably engage, such that the top portion and the base portion are compressibly drawn toward one another between the two rows of nut teeth via frictional sliding contact of the wedges on the flange teeth past the wedges on the nut teeth.

In the second exemplary embodiment, a generally linear motion is applied to the top and base portions relative to the nut portion, and this motion may be made in any suitable manner, such as by fixing the position of the base portion and by applying hydraulic pressure to the lid portion, such that generally linear motion of the lid portion occurs relative to the base portion, the generally linear motion of the lid portion tending to be opposed by the nut portion via the lid portion flange wedges engaging the first row of the nut wedges, and the second row of nut wedges being oppositely engaged via the base portion flange wedges.

Among other advantages, the present invention allows the containment vessel to be assembled and disassembled in much less time than prior art systems. In addition, the failure rate and number of failing components of the present invention are each much lower than prior art vessels that include clamps or bolts. Further, the replaceable wedges on the engaging teeth of some embodiments of the present invention allow simple, quick, and relatively inexpensive replacement of the component typically receiving the most wear in use.

Additional advantages and novel features of the invention will be set forth in part in the description that follows, and in part will become more apparent to those skilled in the art upon examination of the following or upon learning by practice of the invention.

DETAILED DESCRIPTION

The present invention provides a pressurizable chamber device or containment vessel and method of use thereof. In one embodiment, the present invention provides a vessel or chamber device that includes two chamber portions, a lid portion and a base portion, that are drawn toward one another via a nut portion. In one embodiment, the lid portion and the base portion each include concave surfaces that matingly fit together, such that an internal chamber is formed by the combined concave surfaces of the lid and base portions when fit together.

FIG. 1 is an exploded view of an exemplary containment vessel having a generally circular profile upon assembly, in accordance with one embodiment of the present invention. As shown in FIG. 1, the pressurizable chamber device or containment vessel 1 of this embodiment includes a lid portion 10, a base portion 20, and a ring portion 30, also interchangeably referred to herein as a “nut portion.” In the embodiment shown, the lid portion 10 has a concave surface within its interior and the base portion 20 has a concave surface 21 within its interior (such concave surfaces also interchangeably referred to herein as “interior cavities”). The lid portion 10 and the base portion matingly fit together such that the lid portion flange 14 and the base portion flange 24 are generally aligned, and an internal chamber is formed by the combined concave surfaces of the lid portion and the base portion 21 when so mated. Lines or other conduits are connectable to couplings or other connectors for communicating pressurized fluid or other material within the conduits with the interior of the formed internal chamber. (See also FIG. 3 and accompanying description, below.)

In the embodiment of FIG. 1, and as further shown in the partial cross-sectional view of FIG. 2A, the flanges 14, 24, each have a groove 15, 25 therein, such that a flexible seal element 50 is fittable into the grooves 15, 25 of both the lid portion flange 14 and the base portion flange 24 when matingly fit together. The flexible seal element 50, which may, for example, have an uncompressed thickness of about ⅜″, maintains a gap between the lid portion flange 14 and the base portion flange 24 when sandwiched therebetween in an uncompressed position, and may have a lesser thickness A (e.g., about ½″) upon being compressed, as further shown in the partial cross-sectional view of FIG. 2B. The flexible seal element 50 of this embodiment is compressible, such that the lid portion 10 and the base portion 20 may be drawn toward one another, compressing the flexible seal element 50, so as to maintain a seal therebetween, and thereby sealing the volume V of the internal chamber formed by the concave surfaces of the lid portion 10 and the base potion 20, as shown in cross section in FIG. 3. A pressure, such as a resin pressure that may be precisely regulated, may then be applied (e.g., via pressure delivered by lines or other conduits connected to openings in the lid portion 10 and/or the base portion 20), for example, to a mold contained within the internal chamber, such as a mold containing resins and fibers for producing a molded part or other product.

As best shown in FIG. 1, the outer flanges 14, 24 of each of the lid portion 10 and the base portion 20, respectively, has a plurality of teeth (also referred to interchangeably herein as “dogs”) 17, 27 extending therefrom. As shown in cross-section in FIG. 4A, each of the teeth (or some of the teeth) 17 has a wedge 118 attached thereto or comprising a portion thereof. The wedge 118 may be attached to the tooth 17 permanently, or semi-permanently, for example, such as via one or more screws, adhesives, welds, or other attachment mechanisms. One advantage of semi-permanently attaching each wedge 118 is that such a wedge 118 may be replaced easily, for example, when worn.

In the embodiment shown in FIG. 1, the nut portion 30 is ring-shaped, having an interior surface 31 that includes a plurality of nut teeth 32 a, 32 b arranged in two rows extending from the interior surface 31, a first row of teeth 32 a being located near a first edge 34 of the nut portion 30 and the second row of teeth 32 b being located near a second edge 35 of the nut portion 30. Each nut tooth (or some of the nut teeth) 32 a, 32 b has an attached wedge or comprises a wedge portion, the wedges being located so as to extend from the side of the nut tooth 32 a, 32 b to which the wedge is attached in a direction opposite the side of the nut tooth 32 a, 32 b located near the side edge 34, 35, respectively, of the nut portion 30 (i.e., the wedges thereby extending internally toward one another).

In one embodiment, the rows of nut teeth 32 a, 32 b are spaced such that the rows of flange teeth of the top potion 10 and base portion 20 may be passed therebetween, and then, upon rotational motion of the top portion 10 and the base portion 20 relative to the nut portion 30, the nut teeth 32 a, 32 b may be engaged with the flange teeth 17, 27, respectively, as further described below with reference to FIGS. 4B and 4C, so as to produce a compressing force between the top portion 10 and base portion 20 via sandwiched engagement of flange portions 14, 24 between the nut teeth 32 a, 32 b.

As shown in the partial cross-sectional view of FIG. 4B, each tooth (or some of the teeth) 17 located on the flange 14 of the top portion 10, as shown in FIG. 1, has a wedge 118 on or comprising its upper surface, as shown in FIG. 4B, and each tooth (or some of the teeth) 32 a in the first row of the nut portion 30, as shown in FIG. 1, has a wedge 33 a on or comprising its lower surface, as shown in FIG. 4B. Upon engagement of wedges 118 of the teeth 17 of the top portion 10 with the wedges 33 a of the teeth 32 a of the nut portion 30, as shown in FIG. 1, such as occurs when a rotational force is applied to the top portion 10 relative to the nut portion 30, as shown in FIG. 1, the interaction of the wedge portions 118, 33 a produces a downward force F₁ as shown in FIG. 4B on each wedged tooth 17 of the top portion 10, and thus an overall downward force on the top portion 10, as shown in FIG. 1.

Similarly, as shown in FIG. 4C, each tooth (or some of the teeth) 27 on the flange 24 of the base portion 20 has a wedge 28 on or comprising its lower surface, as shown in FIG. 4C, and each tooth (or some of the teeth) 32 b in the second row of the nut portion 30 has a wedge 33 b on or comprising its upper surface, as shown in FIG. 4C. Upon engagement of the wedges 28 of the teeth 27 of the base portion 20, as shown in FIG. 1, with the wedges 33 b of the teeth 32 b of the nut portion 30, as shown in FIG. 1, such as occurs when a rotational force is applied to the nut portion 30, relative to the base portion 20, as shown in FIG. 1, the interaction of the wedge portions 28, 33 b produces an upward force F₂, as shown in FIG. 4C, on each tooth 27 of the base portion 20, as shown in FIG. 1, and thus an overall upward force on the base portion 20, as shown in FIG. 1.

The combined downward force of the top portion 10 and upward force of the base portion 20, as shown in FIG. 1, compresses the flexible seal element 50, as shown in FIGS. 2B and 3, thereby sealing the volume V of the internal chamber formed by the concave portions of the top portion 10 and base portion 20, as shown in FIG. 3.

FIG. 5 illustrates a close up of a section of an exemplary ring portion 30 of a containment vessel, in accordance with an embodiment of the present invention.

Thus, in the embodiment of FIGS. 1-5, the top and base portions 10, 20 have generally circularly shaped flanges 14, 24, and each row of the nut teeth 32 a, 32 b is spaced such that the teeth 17, 27 extending from the generally circular flanges 14, 24 of the top and base portions 10, 20, respectively, may pass between the nut teeth 32 a, 32 b into the inner portion 31 of the nut portion 30, and, upon rotation of the nut portion 30 relative to the top and base portions 10, 20, the wedges 33 a, 33 b of the nut teeth 32 a, 33 b and the wedges of the flange teeth 17, 27 meshably engage, such that the top portion 10 and the base portion 20 are compressibly drawn toward one another between the two rows of nut teeth 32 via passing of the wedges on the flange teeth 17, 27 past the wedges on the nut teeth 32. In some embodiments, such motion and engagement of the teeth and wedges may be eased, for example, via use of an applied lubricant.

In the exemplary embodiment of FIGS. 1-5, the rotation of the top and base portions 10, 20 relative to the nut portion 30 may be made in any suitable manner, such as by fixing the position of the base portion 20 and by applying hydraulic pressure to the lid portion 10 (e.g., via vanes 18), such that rotation in rotary direction G of the lid portion 10 occurs relative to the base portion 20, the direction of rotation G of the lid portion 10 tending to be opposed by the nut portion 30 via the lid portion flange wedges 118 engaging a first row of the nut wedges 33 a, and the second row of nut wedges 33 b being oppositely engaged via the base portion flange wedges 28. Similarly, the top and base portions 10, 30 may be fixably held, for example, and the nut portion 20 rotated relative thereto, such as via application of a hydraulic pressure to the nut portion 20.

As shown in FIGS. 1-5, the flanges and teeth may generally extend outwardly from the top and base portions, and the nut teeth may extend inwardly from the nut portion. The flanges and teeth may likewise extend inwardly from the top and/or bottom portions, and teeth may likewise extend inwardly from the nut portion.

FIG. 6 shows an exploded view of an exemplary containment vessel having a pair of parallel sides, in accordance with another embodiment of the present invention. As shown in FIG. 6, the containment vessel 100 of this embodiment includes a top portion 110, a base portion 120, and a nut portion 130. The top portion 110 has at least two parallel sides 110 a, 110 b, the base portion 120 has at least two parallel sides 120 a, 120 b, and the nut portion 130 has at least two parallel sides 130 a, 130 b. The top portion 110 also includes a first formed chamber portion 111, and the base portion 120 includes a second formed chamber portion 121, such that, when the top portion 110 and the base portion 120 are fit together, a internal chamber forms from the first formed chamber portion 111 and the second formed chamber portion 121.

Similarly to the operation of embodiment of FIGS. 1-5, in the embodiment shown in FIG. 6, the top portion 110 of the containment vessel 100 includes an outer flange 112 having rows of teeth 113, each tooth (or some teeth) 113 having an attached wedge or comprising a wedge portion on the upper side of the tooth 113, as viewed in FIG. 6. The base portion 120 likewise has an outer flange 122 having rows of teeth 123, with each tooth (or some teeth) 123 having an attached wedge or comprising a wedge portion on the lower side of the tooth 123, as viewed in FIG. 6. The nut portion 130 includes a first pair of parallel rows of teeth 131, 132 on one of the parallel sides 130 b, and a second pair of parallel rows of teeth on the second of the parallel sides 130 a. Each of the teeth (or some teeth) 131 in the first parallel row has an attached wedge or comprises a wedge portion on the bottom side of the tooth 131, as shown in FIG. 6, and each of the teeth (or some of the teeth) 132 in the second parallel row has an attached wedge or comprises a wedge portion on the upper side of the tooth 132, as shown in FIG. 6. Similarly, each of the teeth (or some of the teeth) in a first row on the second side 130 a has a wedge on the bottom side, as shown in FIG. 6, and each of the teeth (or some of the teeth) in a second row on the second side 130 a has a wedge on the upper side, as shown in FIG. 6.

Upon assembly, the teeth 113 of the top portion 110 are passed between the rows of teeth 131 in the nut portion 130, and the teeth 123 of the base portion 120 are passed between the rows of teeth 132 in the nut portion 130. Upon enagement of the teeth 113, 123 of the top and base portions 110, 120 with the teeth 131, 132 of the nut portion 130, the top portion 110 and the base portion 120 are driven toward one another via application of a generally linear motion of the top and base portions 110, 120, for example, relative to the nut portion 130, the interaction of wedges of the teeth 113, 123 and 131, 132 producing a downward force on the top portion 110 and an upward force on the base portion 120, as shown in FIG. 6, thereby compressably sealing the chamber (e.g., via use of a compressable seal between the top and base portions 110, 120) formed by the abutting first and second chamber portions 111, 121 of the top portion 110 and base portion 120, respectively.

For example, a force K having a direction parallel to the two parallel sides 110 a, 110 b of the top portion 110 is applied to the top portion 110. The wedges attached to the teeth 113 of the top portion 110 interact with the wedges attached to the teeth 131 in the first parallel row of the nut portion 130, so as to produce a downward force on the top portion 110, as shown in FIG. 6. The force applied to the top portion 110 tends thereby to apply a force in the same direction to the nut portion 130. Similarly, the wedges attached to the teeth 132 in the second parallel row of the nut portion 130 interact with the wedges attached to the teeth 123 of the base portion 120, so as to produce an upward force on the base portion 120, as shown in FIG. 6, such interaction occurring as a result of the fixed base portion opposing the force in direction K produced on the nut portion 130, as a result of the applied force from the top portion 110 on the nut portion 130, as further explained below.

The overall compression between the top portion 110 and the base portion 120, as shown in FIG. 6, may be accomplished, for example, as shown in FIG. 7 (containing a representative cross-section of pairs of teeth 131, 113 and 132, 123 of the top, nut, and base portions 110, 130, 120), by appropriately fixing the position of the base portion 120 (as shown in FIG. 6) and by orienting the wedges attached to the flange and nut teeth, as shown in FIG. 7, such that the wedges W₁₁₃ of the top portion teeth 113 are oriented in the same direction as the wedges W₁₃₂ of the second row of the teeth 132 of the nut portion 130 (as shown in FIG. 6), and such that the wedges W₁₃₁ of the first row of teeth 131 of the nut portion 130 (as shown in FIG. 6) are oriented in the same direction as the wedges W₁₂₃ of the teeth 123 of the base portion 120, as shown in FIG. 6.

A linear force in direction K applied to the top portion (and thus to teeth wedges W₁₁₃) produces a downward force (in direction F₃) on the top portion as a result of the interaction of the teeth wedges W₁₁₃ of the top portion with the teeth wedges W₁₃₁ of the nut portion. The linear force in direction K tends to produce a resulting force in direction K upon the base portion via the nut portion, which is opposed by the fixed base portion, as a result of interaction of the teeth wedges W₁₁₃ of the top portion with the teeth W₁₃₁ of the nut portion and interaction of the teeth wedges W₁₃₂ of the nut portion with the teeth wedges W₁₂₃ of the base portion. As a result, a downward force (in direction F₄) is produced on the nut portion (relative to the fixed base portion). The downward force (in direction F₃) of the top portion and the downward force (in direction F₄) on the nut portion in combination (also further adding to the downward force on the top portion via the nut portion) draws the top portion and the base portion toward one another, such that a tightly sealed internal chamber may be produced by the chamber portions of the top and base portions.

Although exemplary embodiments of the present invention have now been discussed in accordance with the above advantages, it will be appreciated by one of ordinary skill in the art that these examples are merely illustrative of the invention and that numerous variations and/or modifications may be made without departing from the spirit or scope invention.
